Note: 01/2003 Product: Elektra 2000 Serial Number : 001 ~ 450 Description: Occasional mute activation by high talkers.

Detailed Description

If someone using the repeater has a high timbre voice and the RX audio is set too high, a false DTMF may occur causing an audio gap as the audio mute is activated.

Solution

The easiest way is lowering the RX audio and rising the TX audio to compensate. If this is not an option, changing R28 value from 470K to 560K or even to 680K should do the job. This changing will add a extra delay for DTMF decoding, helping to avoid false detection.

Ps: This situation will not occur with DTMF mute function disabled.
